Composer is the recommended installation method.
To add Nazg\Glue to your project, add the following to your composer.json then re-run composer:

  "require": {
    "nazg/glue": "^1.4"
  }

Run Composer commands using HHVM like so:

$ composer install

In addition, you will need to use hhvm-autoload as your autoloader.

or

$ composer require nazg/glue

Usage

First steps

Create Class

interface AnyInterface {

}
final class Any implements AnyInterface {
  // any
}

Bindings

use type Nazg\Glue\Container;
use type Nazg\Glue\Scope;

$container = new Container();
$container->bind(AnyInterface::class)
  ->to(Mock::class)
  ->in(Scope::PROTOTYPE);
\HH\Asio\join($container->lockAsync());

dependencies will be automatically resolved

$container->get(AnyInterface::class);

Scopes

use the Nazg\Glue\Scope enum.

enum Scope : int {
  PROTOTYPE = 0;
  SINGLETON = 1;
}
enum
Nazg\Glue\Scope\PROTOTYPE single instance
Nazg\Glue\Scope\SINGLETON prototype instance

Providers

use \Nazg\Glue\ProviderInterface.

use type Nazg\Glue\ProviderInterface;

final class AnyProvider implements ProviderInterface<AnyInterface> {

  public function get(): AnyInterface {
    return new Any();
  }
}
$container->bind(AnyInterface::class)
  ->provider(new AnyProvider();

Binding Serialization Cache

use type Nazg\Glue\ContainerBuilder;

$builder = new ContainerBuilder(true, 'apc.cache.key.name');
// return a \Nazg\Glue\CachedContainer Instance
$container = $builder->make();
